The passenger cabin exhaust air goes through floor grilles to the recirculation system or overboard.

A. In order to avoid edge effects on vibration routes that may misinterpret test readings, the test pitot should be moved so that the detection route moves along the surface edge to provide a constant edge for the test pitot detection.

B. To avoid edge effects on vibration paths which give a test reading that may be misinterpreted, the test probe should be moved so that the inspection path follows the surface edge, giving a constant edge for the test probe to inspect.

C. The detector should be removed along the inspection route which follows the surface edge to provide an immobile edge to detect, so as to avoid the effects on vibration route edge which may lead to the misunderstanding of the test reading.
